Moosomin Lake

Moosomin Lake,[1] also known as Moosomin Reservoir, is a man-made lake in south-eastern part of the Canadian province of Saskatchewan. Created by the damming of Pipestone Creek in 1954, Moosomin Lake is located about 10 kilometres (6.2 mi) south of the town of Moosomin and is in the Souris River watershed. The reservoir's uses include irrigation, water supply, and recreation. Moosomin Lake Regional Park is on lake's western shore.[2]

The town of Moosomin gets its drinking water from wells alongside the lake. From the wells, the water is piped to town.

In 2011, much of the Souris River watershed flooded in a greater-than-one-in-a-hundred year flood event. While the well shacks are a few feet higher than the normal water level in Moosomin Lake, due to the rising water levels, sandbags had to be used around the wells to protect them from being contaminated. After the waters receded, permanent three-foot clay dykes were built at the well site to protect the wells from future potential flooding.[3][4]

Geology

Moosomin Lake sits in the Pipestone Valley, which was created about 15,000 years ago with the melting of the last ice age. The valley was cut by the melting waters from glacial Lake Indian Head and is called the Pipestone Spillway.[5]

Moosomin Dam

The construction of Moosomin Dam (50.0478°N 101.6905°W / 50.0478; -101.6905) along the Pipestone Creek began in 1953 and work was completed by November 1954. It is an earth-filled embankment dam located at the south-east corner of Moosomin Lake that is 13.5 metres (44 ft) high with an uncontrolled overflow concrete spillway and a gated riparian outlet. The maximum discharge capacity is 448 m3 (15,800 cu ft) per second. The total length of the reservoir when full is 8 kilometres (5.0 mi) long with a total storage capacity of 11,156 dam3 (394,000,000 cu ft). The total amount of land flooded for the reservoir is 389 ha (960 acres).[6]

Moosomin Lake Regional Park

Moosomin Lake Regional Park (50.0784°N 101.7106°W / 50.0784; -101.7106)[7] opened up in 1955 along the western shore of the lake. The regional park is about 14 kilometres (8.7 mi) from the town of Moosomin and can be accessed from Highway 709, which is just off Highway 8. The park features camping, swimming, and boating. There are 125 serviced campsites plus unserviced over-flow sites. The beach area of the park has a sandy beach, a picnic area, and a playground.[8] There are also boat launches and a marina that was built in 2015.[9] Just outside the park, to the east near the dam and along Highway 8, is the 9-hole Pipestone Hills Golf Course.[10]
